Vivi hadn't thought much of Mikoto talking to herself, he was distracted enough to reach the conclusion that she was just saying she was ready to fight him. He placed the ether back in his pocket, picking up his staff and following the group.

"We're going to win." He said to Serah, shaking his head. He wasn't entirely sure of it himself but for once, thinking about it too much was helping. Losing and not fighting had the same consequences, letting fear of losing stop them from fighting was probably a little pointless. And they'd beaten him before with less people. And Edward had said he could probably stop Garland from using his magic.

For once, even if it was mostly false bravado, Vivi was fairly confident.
